IMPROVEMENT `IN MAKING CORRUGATED FUNNEL-SPOUTS.

Specification forming part of Letters Patent No. 46,162, dated January 31, 1865.

To a-IZ whom it may concern:

Be it known that l, JONATHAN WALTON, of Brooklyn oity, in the county ot' Kings and State of New York, have invented a new and useful Improvement in Making Corrugated Funnel-Spouts; and l do hereby derlare that the ollowing is a full, clear, and exact dest-ription ot' the construction andoperation of the same, reference being had to the annexed drawings, making a part of this specification, in whioh- Figures l and 2 are horizontal views of the corrugator; Fig. 3, the end view of same. Fig. 4 is alluted arbor. Figs. 5 and 6 are two tinted halt' -boxes, horizontallyr represented, and Fig. 7 is an end view ot'same.

In carrying out my invention l employ two pieces of eastiron or any other metal with grooves, as shown in Figs. l and 2, and marked A and B. placed one on the other and kept in their proper position by two pins, (marked O and 1),)

The pieces of grooved metal are proper shape between them. Vhen the motion ofsaid press brings the two plates E F together, the desired form is given.

Fig. 4 is a luted arbor, upon which the grooved blank of tin is turned, and is used in connection with the two half-boxes, (marked 5 and 6,) for the purpose ot' closing and finishing the spout. These boxes are used when arranged as shown in Fig. 7, one-halt' of which is supported by spiral springs, as shown in Fig. 3. These are also placed between a press, having the tluted arbor with a spout ou it inside ot' them.

The object ot' this invention is to make a strong ventilating-spout for tunnels.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

rlhe process of making corrugated funnelspouts by first crimping the .fiat plate between corrugated plates E F, and afterward turning it around a longitudinallycorrugated mandrel and pressing it thereon between coras shown in Fig. 3, the uppermost piece of l rngated dies, all as hereinbefore described.

grooved metal being supported by two spiral sp rings, (shown on pins C and D, in thetorm ot' sloping lines.) These grooved pieces of metal, when in position as shown in Fig. 3, are placed under a press, having a piece of tin the JONATHAN VALTON.
